Air guiding device and its manufacturing and assembling method

Abstract

The invention discloses an air guide device and a manufacturing and assembling method of the air guide device. The air guide device comprises at least one air guide section, each air guide section comprises an air guide section body composed of a top plate and a bottom plate, reinforcement ribs are arranged inside the air guide section bodies, and each of the top plates, the bottom plates and the reinforcement ribs is made of a fiber reinforcement composite material inner layer and a fiber reinforcement composite material outer layer. The manufacturing and assembling method includes the steps that (1), the fiber reinforcement composite material inner layers, the fiber reinforcement composite material outer layers and light sandwich layers are manufactured and used for forming the top plate, the bottom plate and the reinforcement rib, so that one air guide section is formed; (2), the preset number of air guide sections are manufactured and connected with a main beam of a bridge through bolts, and the air guide sections are connected through bolts. The air guide device has the advantages of being light, high in strength and corrosion performance and easy to connect with the main beam, and the manufacturing and assembling method is simple and convenient to implement.

Description

technical field [0001] The invention relates to an auxiliary structure for improving the wind resistance characteristics of a main structure, in particular to an air guiding device used in long-span bridge structures and high-rise building structures and a manufacturing and assembling method thereof. Background technique [0002] Generally, for long-span bridges, since the width and height of the girder are much smaller than the span, the bridge is significantly sensitive to wind vibration. Since the Tacoma Suspension Bridge in Washington State, USA was destroyed by wind vibration in 1940, people began to pay attention to the wind-resistant design of the bridge. In recent years, with the application of some lightweight and high-strength building materials, the sensitivity of bridges to wind has been further increased, making the problem of wind vibration of bridges more prominent. The air guide device of the bridge is a design measure taken to reduce the resonance caused by...

AI Technical Summary

Problems solved by technology

Existing large-span bridge air guides mostly use steel structures, which are easy to process and connect, but there are also problems such as heavy weight, difficult maintenance, and easy deformation of welding, especially in marine or atmospheric corrosion environments, the surface of steel air guides needs to be regularly repaired Anti-corrosion treatment

In the actual bridge maintenance work, since the air guide device is in the cantilever state in the air, the maintenance personnel cannot reach the position of the air guide device, which brings certain difficulties to the later repair and maintenance of the bridge air guide device
